I have three service that I need to expose via istio ingress gateway, i have setup those services dns records to point to the ingress gateway load balancer but i have not succeded to make it work.
The gateway and virtual service config file :
apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
name: test-gateway
spec:
selector:
istio: ingressgateway # use istio default controller
servers:
- port:
number: 80
name: http
protocol: HTTP
hosts:
- "*.mywebsite.io"
---
apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
name: virtualservice
spec:
hosts:
- "*.mywebsite.io"
gateways:
- test-gateway
http:
- name: "api-gateway"
match:
- uri:
exact: "gateway.mywebsite.io"
route:
- destination:
host: gateway.default.svc.cluster.local
port:
number: 8080
- name: "visitor-service"
match:
- uri:
exact: "visitor-service.mywebsite.io"
route:
- destination:
host: visitor-service.default.svc.cluster.local
port:
number: 8000
- name: "auth-service"
match:
- uri:
exact: "auth-service.mywebsite.io"
route:
- destination:
host: auth-service.default.svc.cluster.local
port:
number: 3004
I guess the URI part of the HttpMatchRequest does not work that way. Try to add VirtualServices for each subdomain, i.e. something like.
apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
name: gateway-virtualservice
spec:
hosts:
- "gateway.mywebsite.io"
gateways:
- test-gateway
http:
- name: "api-gateway"
match:
- uri:
exact: "/" #or prefix
route:
- destination:
host: gateway.default.svc.cluster.local
port:
number: 8080
---
apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
name: visitor-virtualservice
spec:
hosts:
- "visitor-service.mywebsite.io"
gateways:
- test-gateway
http:
- name: "visitor-service"
match:
- uri:
exact: "/"
route:
- destination:
host: visitor-service.default.svc.cluster.local
port:
number: 8000
